摘要：
The circuit breaker current/time characteristic value at which the bimetal (5) in a thermal trip assembly (1) actuates a trip mechanism (11) is adjusted by an adjustable coupler (15) that includes first and second pivoted members (17,21) separately rotatable about a common pivot axis (23). Deflection of the bimetal (5) by an overload current causes rotation of the first pivoted member (17), which is coupled by a coupling member (29) extending parallel to the common axis (23) into the second pivoted member (21) which rotates to actuate the trip mechanism (11). A positioner (37) moves the coupling member (29) toward and away from the common pivot axis (23) to adjust the amount of deflection of the bimetal (5) needed to actuate the trip mechanism (11).
